How do Apple Search Ads (ASA) compare to Google App Campaigns in terms of average Cost Per Install (CPI) and Day 30 user retention benchmarks?
Short answer
Apple Search Ads yields higher Day 30 user retention rates of 8% to 14% at an average Cost Per Install of $1.80 to $4.50. In contrast, Google App Campaigns delivers lower install costs between $1.00 and $2.50 with lower retention of 3% to 7%. Teams should allocate 60% to 70% of initial iOS budgets to high-intent Apple Search Ads before scaling through Google.
Apple Search Ads delivers higher Day 30 retention rates of 8% to 14% at an average Cost Per Install of $1.80 to $4.50, whereas Google App Campaigns achieves lower acquisition costs of $1.00 to $2.50 alongside lower retention rates of 3% to 7%.
Mobile app growth teams encounter escalating acquisition costs alongside steep post-install churn across major paid advertising channels. Because native App Store search conversion averages over 60% in industry benchmarks, true acquisition efficiency depends on downstream retention and customer lifetime value rather than low initial install pricing alone.
If you only do one thing: Allocate 60% to 70% of your initial iOS budget to Apple Search Ads high-intent keyword tiers before scaling broader reach through Google App Campaigns optimized for post-install actions.
- Intent and Acquisition Cost: Apple Search Ads (ASA) captures active user search queries inside the App Store, producing average Cost Per Install (CPI) benchmarks between $1.80 and $4.50, whereas Google App Campaigns (GAC) utilizes multi-network distribution to drive blended CPIs between $1.00 and $2.50.
- Day 30 Retention Rates: ASA users average Day 30 (D30) retention between 8% and 14% due to explicit search intent at the point of download, while GAC's broader algorithmic inventory yields average D30 retention between 3% and 7%.
- Targeting and Structure: ASA uses keyword match types across four campaign structures (Brand, Category, Competitor, and Discovery), whereas GAC operates through automated bidding that distributes creative across Search, YouTube, Google Play, Discover, and the Google Display Network.
- Conversion Efficiency: ASA averages tap-to-install rates between 50% and 67.2% on native search placements, whereas GAC trades lower click-to-install rates for higher cross-platform volume across both iOS and Android ecosystems.
- Attribution Windows: ASA provides deterministic, real-time attribution data through native Apple frameworks, while GAC iOS campaigns rely on Apple's SKAdNetwork framework, which introduces delayed reporting intervals of 24 to 72 hours.
- Watch out for: Running automated ASA Discovery campaigns without negative keyword lists, which exhausts daily spend on generic search terms and inflates blended CPI above $6.00 without boosting retention.
- Watch out for: Setting Google App Campaigns to bid for raw install volume rather than target in-app conversion events (tCPA), which fills the funnel with non-converting users who drop off within 48 hours.
